I just bought an SD-8 for my 20" wheeled Bike Friday Haul-a-Day. Can't wait to build up the wheel and see how it performs. I have other bikes with Shimano and Schmidt hubs, but neither rolling on 20" wheels. I'm hoping for low drag and imperceptible vibration, which is what I get with the Schmid

Well, it's clear to me that the drag-vs-light remains a consideration in choosing between an SP SV-8 and SP PV-8. Even with my SP PV-8 hub (and my SON28, for that matter), there have been a few occasions when I wished my light were brighter at a relatively slow speed when it was in fact brighter

The hubs that are for smaller wheels will generate full light with modern LED lights at very slow speeds, something less than 5mph, in my experience. In fact, only when I spin my hub by hand, or walk the bike, do I notice less than full output with my 80 lux light. People overestimate the speed r

Kellie, I believe you are talking about the SV-8 and not the PV-8, which has full voltage per the German specs. On Sat, Jun 6, 2015 at 11:30 AM, Kellie wrote: > Don't count out the Shimano 3N80. I just put one on my new Saluki, and I > love it. A few more dollars than the ID and more powerful.

Those numbers do seem satisfactory. I certainly don't have any precise measurements of my own. Perhaps if I do get another dynamo wheel I'll go with a lower-drag ("smaller wheel") version. My understanding is that the current "larger wheel" dynamo output specs are something of a legacy from the

I have an SP PV-8 hub on one Hillborne and a current-generation SON28 on another Hillborne. I like them both just fine. I may end up getting another dynamo'd wheel in the future and, barring near-future failure of the one I have, will probably get another SP PV-8 just because it's >$150 cheaper.

I've had a shutter precision SD-8 for over a year and a half, and so far it's great. I never noticed the drag, have only noticed vibration once or twice on long downhills with the light on. It's the only dynohub I've owned but I've worked on bikes with all types. In hand, the rotation seems

Don't count out the Shimano 3N80. I just put one on my new Saluki, and I love it. A few more dollars than the ID and more powerful. Check the voltage output, the ID will not power all dynamo lights. On Friday, June 5, 2015 at 10:53:44 PM UTC-7, Don Funke wrote: > > Anyone have experience with t
